Massive Crank Harmonic Damper Balancer Pulley Bolt LS1 Camaro GTO Corvette ARPTruly superior strength is needed on this most critical of load bearing fasteners. The crankshaft sees immense kinetic energy! Both twisting and lateral loads are exerted on this one area, and to an even greater degree on belt driven supercharged cars. OEM fasteners are one time use they stretch and must be replaced, so upgrading with the Massive Speed Precision unit is a "no brainer". Grade 12. 9 197,000 PSI tensile strength 12 point flanged bolt

Dogs enjoy them
Pattern Name: Half Ears (15-pack)
The brand I usually get them was not available at this time from Amazon and my other retailer only had large white cow ears, which don't look appealing to me even though my schnoodle is in the with knawing on them , the sound of him taking them apart in bed in the middle of the night is something to wake up to. So I was glad to have this recommended as a substitute, and they look like they are flavor to them,the are on assorted sizes and the dogs seem to like them and in the long run that's all that matters

These pig ears are big
Pattern Name: Full Ears (25-pack)
These pig ears are pretty big, great for large dogs. My dogs love them! I keep them refrigerated, for freshness and my dogs love them cold.

Good but a bit overpriced
Pattern Name: Half Ears (15-pack)
I like these as they are a good size and not as greasy as others. I have 4 dogs that get one each evening. It would be nice if they were a bit cheaper.

Apparently delicious to dogs!
Pattern Name: Half Ears (15-pack)
Bought these hoping they wouldn't be too large for my 10 lb. dog, and found that she loves them so much it doesn't matter that she can't finish one all at once. I think they are her favorite treat, and can last her days, so it is a great deal both for her, and for my wallet! (she also doesn't get them more than once every week or two!)
